The adaptive equalizer of the present invention estimates a channel impulse response vector h in a channel impulse response estimator, outputs a result to a channel impulse response convertor. The a channel impulse response convertor removes interference components from the channel impulse response vector h, outputs a channel impulse response vector h' to an equalizer. The equalizer sets up, based on the channel impulse response vector h', internal parameters, and equalizes, based on the internal parameters, reception signals. By configuring as above, a distortion by intersymbol interference and a deterioration of reception performance by Co-channel interference waves can be prevented. :

L'invention est un égaliseur adaptatif qui évalue un vecteur de réponse impulsionnelle h et transmet le résultat à un convertisseur de réponse impulsionnelle. Celui-ci élimine les parasites du vecteur de réponse impulsionnelle h et transmet son signal de sortie, le vecteur de réponse impulsionnelle h', à un égaliseur. En se basant sur le vecteur de réponse impulsionnelle h', cet égaliseur détermine les paramètres internes et, en se basant sur ceux-ci, égalise les signaux de réception. En utilisant ce type de configuration, on peut empêcher la distorsion par brouillage entre les symboles et la dégradation de la performance de réception par brouillage sur le même canal.
